Who's turn is it? Google tts automation

So I’ve just upgraded to Nabu Casa and integrated google home. Now everything is working I was wondering the following;

In The Netherlands we eat an “toetje” after dinner. In our case, our at least my kids it’s a popsicle. This this is, the freezer is in the cellar and every day they both have a discussion who needs to get them. (4&7 years old)

Hou nice would it be that they can ask Google who’s turn it is?
And they hear Google say one of their names…

The this is, my YAML skills are not that advanced and actually do not know where to start this.

Is there anyone who is able to help me with this or give me a push in the right direction?

Much appreciated!
